MACHINE.

SPECIFICATION forming part of Letters Patent No. 595,439, dated December 14, 1897.

Applicant mea March so, 1896.

To all whom t may concern,.-

Be it known that I, HARRY A. Ho UsEMAN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Knitting- Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The machine generally may be such as is illustrated and described in Letters Patent v as is necessary to a clear understanding of the invention forming the subject-matter of this application.

In the drawings, Figure 1 is a side elevation of knitting-cylinder, &c. Fig. 2-is a section on the line w 0c, Fig. 1. Fig. 3 is a section o n line y y, Fig. 1.

D is the cam-cylinder.

Eis the sinker-cam cylinder.

F is the needle-cylinder, and f the needles.

The thread-carrier consists of the frame H, to which is xedly secured the plate A, and secured to a shaft l) is the plate B, having the thread-orifices B and B2.V In the plate A is the slot a, in which in the movement of plate B the thread rests or travels.

C C', respectively, are leaf-springs secured to the plate A, one at each end thereof. The shaft b inds abearin g in and projects through the frame H and has on its end the gearwheel or pinion H', which meshes with the rack H2, connected to the arm I, which is guided and adapted to move vertically in a slot g in the frame H and has at its lower end the cam K. In one position of the plate B the orifice B is in operative position in refer- Serial No. 685,319. (No model.)

ence to the needles, and in the other position the oriiice B2. The plate B is caused to slide upon the plate A, so as to cause the orifices B and B2 to assume these positions by the rack H2 acting on the pinion H', the rack being operated bythe movement of arm I. According to which orifice B' or B2 is in operative position its corresponding thread is in operative position, the idle thread in each case being held bythe corresponding leafspring O or C. j When the plate B moves to bring the orifice out of operative position, the thread corresponding is broken off.

In practice yarns of different color or weight are drawn through the orifices B and B2, or a single thread may be drawn through one orice and a plurality of threads through the other, which latter case, of course, would be the same as the different weight yarn thread first spoken of.

The thread-carrier as a whole may be rotated or reciprocated and changed from rotation to reciprocation in the manner and by the mechanismdescribed and illustrated in my previous patent hereinbefore set out in this specification. The plateB is operated automatically in the operation of the machine in the following manner:

L is a supplemental pattern-chain driven by the same shaft as the pattern-chain in my previous patent hereinbefore cited. Upon this chain at desired points are raised portions Z.

M is an angle-arm supported in suitable guide l on the frame of the machine, having at one end, adjacent to the pattern-chain, the roller M and at the other end the caln M2. The roller M is in line of movement of pattern-chain L and the cam M2 in line of movement of cam K. W'hen the roller M' is on raised portion Z of chain, the cam K strikes the under surface of the cam M2, depressing the arm I, which causes the plate B to move from the right toward the left, and when the roller is on the low portion of the chain the cam K strikes the top surface of the cam M2, elevating the arm I, causing the plate B to move from the left toward the I'ight. A spring N holds the roller M in contact with chain L. The first movement just described brings the thread-orifice B2 into operative position, and

IOO

the second movement just described brings the thread-orice B into operative position. Any desired number of lowr and high places may be placed upon the pattern-chain at the points in the operation of the machine at which it is desired to change from one thread to the other.

From the foregoing it may be seen that with this construction any number of changes from one to the other thread may be made during the operation of the machine. In the drawings the roller M is shown in the high position Zof the chain, and the thread-orifice B2 is in operative position.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-

1. In combination, in a knitting-machine, a thread-carrier, havin g a portion carryin g a plurality of independent threads movable upon the main portion of the thread-carrier to bring the respective threads in and out of operative position, a cam moving with the thread-carrier and connected with the movable portion of lthe thread-carrier, a device adapted atpredetermined points to be brought in line of movement of said cam whereby When said lastmentioned device strikes the cam the movable portion of the thread-carrier is shifted.

2. In a knitting-machine, in co1nbination,a thread-carrier having a movable portion carrying a plurality of independent threads, a cam having a double surface, moving with the thread-carrier and connected with the movable portion of the thread-carrier,a device having two positions, one position in line of movement of one surface, the other in line of movement of the other surface, of the camoperating mechanism for the knitting-machine, connection between said device and the operating mechanism whereby the position of the device is, at predetermined points, shifted, the ca'm being of such character that one surface striking said device shifts the movable portion of the thread-carrier in one direction, and the other surface striking said device shifts the movable portion in the other direction.

3. In a knitting-machine, in combination, a thread -carrier, consisting essentially of a frame, a plate secured upon a shaft havinga bearing in said frame, a pinion on said shaft, a rack meshing with said pinion, an arm carried by and movable in, the thread-carrier frame, and secured to or forming part of the rack, a cam on said arm, and a cam having tWo operative positions controlled by mechanism operated by the operating mechanism of said machine in the line of movement of said pinion-arm cam and adapted in the two positions to move said arm oppositely.

4. In a knitting-machine, in combination, a

thread-carrier, consisting essentially of a frame, a plate secured upon a shaft having a bearing in said frame, a pinion on said shaft, a rack meshing with said pinion, an arm carried by and movable in the thread-carrier frame and secured to or forming part of the rack, a cam on said arm, a secondary arm, a

cam on said arm and a roller on the other end of said arm, a pattern-chain havinghigh and low portions against which chain said roller rests, the cam being in line of movement of said rack-arm cam.

5. In a knittingmachine, a thread-carrier consisting essentially of a frame H, a plate xed to said frame having springs attached to it, a second plate havinga plurality of independent thread-orifices, said last-mentioned plate being movably mounted upon said frame and adapted to move upon said first-mentioned plate.

In testimony of which invention I have hereunto set my hand.
